I have recently acquired an iPad and trying to find the usefulness that people say it is. This particular video by David Kassan( http://davidkassan.com) makes me think there is a creative app that can be used on it. Although, he makes it easy to do, it is certainly not. This is very very good and I didn't think it was possible for the iPad. He states that the model sat in place for 3 hours while he worked this digital painting. Check this time lapse video out.
